Default Alternator Always Charging

Hi all. Drove my coupe accross town the other day, probably 50-60 miles total. Even after driving for a while at speed, the ammeter sat at a consistent 9-10 amps charge. It jumped up to 15- 20 amps after cold start, ammeter still sits at 0 when engine is off.. Tested the voltage at the alternator output and the battery while running and got about 7.5 volts, so around expected. The battery seems to be fine...starts the car reliably. Battery didn't seem to be overcharged when I got home. Thoughts? Bad regulator in the alternator?
